In the oral-history account, the style originated from Mexican cowboys in the early 19th century. These paniolo| (a Hawaiianization of , ) provided guitars, taught the Hawaiians the rudiments of playing, allowing the Hawaiians to develop the style on their own. Musicologists and historians suggest that the story is more complicated, but this is the version that is most often offered by Hawaiian musicians. Slack-key guitar adapted to accompany the rhythms of Hawaiian dancing and the harmonic structures of
Hawaiian music.
The New York Times described the music as "liquid, rippling, and hypnotic". During the 1960s and particularly during the
Hawaiian Cultural Renaissance of the 1970s, slack key experienced a surge in popularity and came to be seen as one of the most genuine expressions of Hawaiian spirit, principally thanks to Gabby Pahinui,
Atta Isaacs,
Leonard Kwan,
Sonny Chillingworth,
Raymond Kāne, and the more modern styles of younger players such as
Keola Beamer, his brother Kapono Beamer,
Peter Moon, and
Haunani Apoliona. During this period, luthiers such as the
Guitar and Lute Workshop in Honolulu specialized in the development and manufacture of guitars custom made to order for slack-key performance. Many prominent Hawaii-based players got their starts during the Cultural Renaissance years: Cindy Combs,
Ledward Kaapana,
George Kahumoku, Jr., his brother Moses Kahumoku,
Dennis Kamakahi,
Ozzie Kotani, three Pahinui brothers (Bla, Cyril, and Martin), the Emerson Brothers and
Owana Salazar. These artists, and slack key in general, have become well known outside Hawaii largely through
George Winston's
Dancing Cat Records record label, which has most often showcased the music in solo settings. One indication of slack key's increasing visibility beyond the Islands is that the first four winners of the
Grammy Award for Best Hawaiian Music Album were slack key collections:
Slack Key Guitar, Volume 2 in 2005,
Masters of Hawaiian Slack Key Guitar, Volume 1 in 2006,
Legends of Hawaiian Slack Key Guitar—Live from Maui and "Treasures of Hawaiian Slack Key Guitar – Live in Concert from Maui." Players from outside Hawaii have also taken up the tradition, for example,
Chet Atkins (who included slack key pieces on two of his albums), Yuki Yamauchi (a student of Raymond Kāne's and an advocate of Hawaiian music in Japan), pianist
George Winston, and Canadian
Jim "Kimo" West (perhaps better known as guitarist with
"Weird Al" Yankovic). ==Techniques and tunings==
